It may be feather light and downy soft, but there’s nothing wimpy about the Klamath Range Half Zip. This pullover offers ample warmth, with a neck zip you can snug up to get toasty or unzip to ventilate more less Columbia’s patented Glacial™ microfleece insulates, breathes and dries quickly, making the Klamath Range an excellent layering piece for changing weather. Thoughtful details, like a zipper garage that spares beards and distinctive side and wrist panel seaming, combine to create a handsome fleece shirt that’s as comfortable in the vineyards as in the wine bar afterward. Authentic fit.
